| Abstract: | Equivalent coefficient of frozen soil layer is an essential parameter showing ablation of frozen soil layer by thermo insulating layer. On the basis of observation results of Wangcun frozen soil testing field in Hebei, the influence of moisture, soil quality and thickness of thermo insulating layer on the equivalent coefficient of frozen soil layer is analysed and the calculating formula of the equivalent coefficient of frozen soil layer is put forward to provide reference basis for the design of thermo insulating layer in this paper. |
